The logical hard disk failure is generally the result of damage to the hard drive data structure like file system. The reason of this crash might be accidental deletion of system files, registry damage, computer virus, power outages, and unexpected system shutdown.

It is also significant to see that in the majority of logical hard drive failure cases, the drive still gets recognized by the BIOS, but would not boot. In case of logical hard drive failure, the data remains intact on the drive, even if the operating system considers it as inaccessible.

There are two basic reasons of logical hard drive failure, which include:

User Errors: It includes accidental deletion of important system files, unintentional hard drive formatting and deletion of hard drive partition/volume. User errors could be fixed by using Do It yourself data recovery software.

System Errors: It is generally the result of application conflicts or operating system corruption. It could take place due to virus attack and the similar reasons. It is also curable using Data recovery software.

Logical hard drive failure can be fixed very easily with the help of data recovery software. Data recovery software are third party tools, designed to meet different users' data recovery needs.
